1. BHint: Use the Solubility Rules found in the Lab 6a Introductory Materials balance the following molecular equations:
To determine the physical states of your products.
Be sure to include the correct formulas for each compound, stoichiometric coefficients, and physical states.
a. _1_ Cu(NO3)2 (aq) + _2_ KOH (aq) → _Cu(OH)2(aq)_ + _2KNO3(aq)_
b. ____ (NH4)2CO3 (aq) + ___ Al(C2H3O2)3 (aq) → _______ + ________
c. ____ K2SO4 (aq) + ____ Mg(NO3)2 (aq) → ________ + ________
ideal gas originally at STP expands irreversibly and isothermally from point A to point B in the Carnot cycle diagram. It then is expanded reversibly and adiabatically from B to C.
a balloon is filled with a gas. the baloons volume is 2.1 l and the gas pressure is 1.7 atm. then the balloon is placed
A 4.305-gram sample of a nonelectrolyte is dissolved in 105 grams of water. The solution freezes at -1.23°C. Calculate the molecular weight of the solute. Kf for water = 1.86°C/m.
If 13.0 g of MgSO4*7H2O is thoroughly heated, what mass of anhydrous magnesium sulfate will remain. Express your answer numerically in grams.
Pipette 10 mL of Reaction Mixture 1 into a 50 mL beaker. Pipette 1 mL of the KMnO4 into the Reaction Mixture, starting the stopwatch immediately.
Plot the Shewhart chart for the mean, and the cusum chart, for these results, and comment on the outcomes.
A researcher determines that 744 J of energy needed to vaporize a 355-mg sample of a liquid at its boiling point. Determine the heat of vaporization and heat of condensation of the substance
Write a five page (body; double-spaced) review of the topic from a public health biology perspective. In your review, include the following- Explain the biological basis of asthma and allergic disease, including an introduction to your chosen focus..
we need to dry something like protein and drugs, how to deal with them to avoid the deactivation phenomenon?
When he measured the concentration of products and reactants (not at equilibrium) under the conditions of human body temperature as 2 micromoles of products and 17.3 micromoles of substrates, what was the current free energy difference at that poi..
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
The freezing points of 0.0935 m ammonium chloride and 0.0378 m ammonium sulfate in water were found to be -0.322 C and 0.173 C. What are the values of the van't Hoff factors for these salts
